Recycling of Waste Tyres: A Possible Option for Deriving Energy

Abstract

Depletion of fossil fuel resources and stringent environmental laws have forced researchers to develop methods to sustainably manage resources. Focus has been gradually shifting towards energy recovery from waste materials which can solve both the problems. One of the major wastes in the automobile sector is automobile tyres. These have an adverse impact on the environment if they are not disposed o properly. Further, tyres are a source of high grade energy hence its improper disposal means wastage of energy. Several methods have been developed to extract energy from waste tyres. One of them is pyrolysis of tyres which produces Tyre Pyrolysis Oil (TPO) by thermal decomposition of tyres. The properties of TPO blends with diesel were analysed and compared with diesel and found that it can also be used as a fuel in compression ignition engine. Experiments were carried out on a single cylinder, four stroke, air-cooled, diesel engine running with dierent blends of TPO from 5% to 20% on volume basis. Experimental results indicated that TPO of 20% blend gave better performance.The Performance and emission characteristics are reported in this thesis.
